The effect is as follows: can effectively take out the sealed packing of oil transportation bent rod pump fast, take out a sealed packing and can save fifteen minutes, solve the difficult problem of taking out old sealed packing when field crew changes the bent rod pump and seal, alleviate operating personnel's intensity of labour.

Description

A special tool for replacing the sealing packing of oil delivery crank pump

technical field

The utility model relates to the technical field of oil production in an oil field, in particular to a special tool for maintenance of an oil delivery crank pump, which is a special tool for replacing the sealing packing of the oil delivery crank pump.

Background technique

At present, in the heavy oil production process, ground crank pumps are often used to input crude oil into the oil gathering station. The space where the rod pump disassembles and assembles the sealing packing is narrow, and it is difficult to take out the old sealing packing with common tools.

Utility model content

The purpose of this utility model is: to provide a special tool for replacing the sealing packing of the oil delivery crank pump, which can effectively and quickly take out the sealing packing of the oil delivery crank pump, and solve the problem of taking out the old seal when the on-site staff replaces the crank pump seal. Problems that are more difficult to root.

The technical scheme adopted by the utility model is: a special tool for replacing the sealing packing of the oil delivery curved rod pump, which is mainly composed of a take-out rod, a tightening sleeve and a wrench. It is composed of three sections of the left-handed screw, the screw head, the slot section and the left-hand screw are on the same straight line on the center line; one end of the take-out rod has a conical screw head, and the root of the screw head is the slot section , the slot section is composed of a cylinder and a square cylinder, and there is a wrench on the square cylinder. The wrench is a rectangular rod, and there is a rectangular groove at one end of the wrench. The width of the rectangular groove of the wrench is the same as that of the slot section. The side lengths of the square cylinders are the same, and the wrench can be inserted on the square cylinder of the slot section. The other end of the take-out rod is a left-handed screw rod, on which a jacking sleeve is connected, and a left-handed thread is arranged in the jacking sleeve.

Briefly describe the process of using the special tool for replacing the sealing packing of the oil delivery crank pump. See Figure 1. When it is necessary to take out the old sealing packing, the screw head 1 will be screwed in to align with the sealing packing, and the tightening sleeve 4 at the rear end of the left-handed screw rod 3 will be pushed in the curved rod pump. Turn the wrench 5 clockwise, and the screw head 1 can be screwed into the sealing packing. At the same time, the tightening sleeve 4 is rotated relative to the take-out rod, and the screw head 1 is pushed to be inserted into the sealing packing. When it is necessary to take out the sealing packing, turn the wrench 5 counterclockwise, and the left-handed screw 3 enters the tightening sleeve 4 . The sealing packing can be easily taken out.

Beneficial effects of the utility model: the utility model is a special tool for replacing the sealing packing of the oil delivery curved rod pump. During use, it can effectively and quickly take out the sealing packing of the oil delivery curved rod pump, and taking out a sealing packing can save Fifteen minutes to solve the problem that it is difficult for the on-site staff to take out the old sealing packing when replacing the crank pump seal, and reduce the labor intensity of the operators.
